John,

You are magnificent! After I modify the kernel setting and recompile and reload, I am able to load my application.

Thank you,
Victor

Hi Victor,

In menuconfig -> kernel settings -> general settings, try enabling 
either the "Permit large allocations" setting, or the "non-power-of-2" 
allocator.

John
